Europa (moon of Jupiter)

Europa is one of Jupiter's largest moons, notable for its smooth, icy surface that appears like a frost-covered shell. Beneath this ice crust, scientists believe there is a vast subsurface ocean of liquid water, potentially harboring conditions suitable for life. The moon's surface is crisscrossed by cracks and ridges caused by the icy shell's shifting and flexing. Europa's environment is extremely cold and exposed to intense radiation from Jupiter, but the possibility of a hidden ocean makes it a prime target in the search for extraterrestrial life within our solar system.
